A University of Michigan student sought for more than a week after a fatal shooting at his residence surrendered to police Thursday, officials said.

Andrew Robert Myrick, 28, turned himself in with his attorneys and was arraigned on a misdemeanor marijuana possession charge. He was released on personal bond following his arraignment Thursday, with several conditions, police said.

Myrick has not been charged in connection with the shooting at his duplex on Jan. 16, but police had been seeking him to interview him as part of their investigation.

A key issue to be decided by prosecutors is whether the shooting was in self-defense. Prosecutors have said they will not rule on the legality of the shooting until the investigation is complete.

Detectives allege that four men broke into Myrick's home near the U-M North Campus, and at least a dozen shots were fired.

David Copeland, 29, was shot multiple times and died at the scene.

Ann Arbor Detective Sgt. Richard Kinsey declined to say Thursday what information - if any - Myrick has provided since he surrendered. He said the investigation is continuing.

Two of the other men accused in the break-in - Copeland's twin brother, Davin, and Derrek Howard, 22 - were arrested and face first-degree home invasion charges. They remain jailed.

Police are still seeking a fourth man Michael Bailey, 20, who also is suspected in the burglary. He is an Ypsilanti Township resident and is believed to be still be in the Ypsilanti area.

Authorities have said the men apparently broke into the home in search of money and/or drugs.

Myrick, an undergraduate engineering student, wasn't at the home when officers arrived the night of the shooting and hadn't been seen since.
